• Logarithmic functions (common logarithm, natural
logarithm)
Logarithmic function calculations are made using the key
operations described below. The result of a calculation is
displayed at the cursor position for input data.
(1) Common logarithm : LOG[45] [INPUT]
(2) Natural logarithm : LN[45] [INPUT]
For a calculation, [ ] is required at all times.
• Absolute value

operations described below. The result of a calculation is
displayed at the cursor position for input data.
(1) Absolute value : ABS[-45] [INPUT]
For a calculation, [ ] is required at all times.
• Rounding
Rounding operations are performed using the key
operations described below. The result of a calculation is
displayed at the cursor position for input data.
(1) Rounding 1 (rounding off to an integer) :
RND[1.234] [INPUT]
(2) Rounding 2 (rounding off "a" to the decimal places
specified by "b") :
RND2[1.267,0.01] [INPUT]
(Note that for a calculation of rounding 2, a special format
using two arguments is required. Enter data according to the
format RND[a,b]. The value of "a" is rounded off to the
decimal places specified by "b". As "b", do not specify a
value other than 1, 0.1, 0.01, and so forth.)
For a calculation, [ ] is required at all times.
